Go with the Canon 450D XSi with A/V out
or a small camera attached to the hot shoe

I understand that some DSLR's have A/V out, in that case, does the video temporarily dissapear when the shutter is triggered?

Om cameras thet don't have A/V out, how to you mount the downlink camera, and what kind of camera do you use?

Thanks,

Jesper

This is what I use.A little pricey but it doesnt mount to the hot shoe,it mounts directly to the eyecup and gives you the view you would have if your eye was there.
With this there is no interuption when triggering the camera etc.Works on any Canon,I have had it on 350's,450's,20d's,5D's etc. it can be made to work on Nikons also.

wjw,

when using the A/V output on the Canon 450D XSi, will the screen go black temporarily when taking a shot?

oakley,

that unit looks really nice, do you remember how much you paid for it? Couldn't find a price on the page.

Thanks,

Jesper

Eye piece

On the Canon xti or the xsi the simplest way is to use an eyepeice adaptor I have made more than my share of these for people. I have been using one forever Just get a good resolution spycam and change the lens to a 16mm and attach it to the Canon eyepeice extender.

Jesper,

You asked twice but couldn't get an answer. I do not have a DSLR so I won't be able to swear on it but my guess would be YES the screen should go blank for a sec. if you are using camera's A/V out for live video.
I do have Canon A640 (point & Shoot) and there is no way to get rid of the blank screen with camera's A/V out hooked up to downlink...

Only if the DSLR has LiveView. Otherwise all you get out of the composite video out is the shot you just took, not real time view through the lens.... remember, prior to LiveView DSLR's the mirror is in the way until you expose to the sensor.

As for temporary blanking.. if you are using a separate board CCD to look through the view finder there will be no noticeable blanking after the shot. LiveView may depend on the camera.

Jesper, keep in mind that that Canons live view dslrs arent able to autofocus when in live view mode.
There are no triggers that work together with that yet, as the focus button is on the * button and not the shutter release...

I was right, you cant use live view along with autofocus on a remote trigger...

Okay, so the Canon 450D XSi won't autofocus when using live view. Will the AF work with the Blip interface if I'm not using live view?

Also, the 18-55 lens that comes with the camera, how well will that work for me (not intending to atempt panos any time soon)?

If youre referring to the blip.com.au urbi, its not compatible with the 450 at all.

18mm(28mm effective) is to tight for AP, IMO, but its usable if you go high enough, heres a pic with that combination
